ABSTRACT This paper presents new tuning rules for PID controllers based on loop shaping. Previous research has shown that maximization of the integral gain subject to constraints on the maximum sensitivity is an efficient design method for PI controllers, but that additional constraints are needed for design of PID controllers. In this paper, an additional constraint is obtained by restricting the ratio between integral time and derivative time. It is shown that this gives a numerically efficient method that gives good results for a large class of processes.
